CONCRETE CAR.

Specification of Letters Patent.

Application filed July 29, 1918. Serial No. 247,168.

To all whom it may concern:

Be it known that I, Josnrn B. STRAUSS, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Concrete Cars. of which the following is a specification.

This invention relates to a concrete car and has for its object to provide a new and improved 'ar. of this description The in vention has among other objects to provide a concrete car reinforced by metal in such a manner as to takecare of the severe strains and properly transmit them into the concrete, thereby producing a strong and durable structure capable of withstandin; shocks and strains due to railway service. The invention is illustrated in the accompanying drawings wherein- Figure 1 is a. side elevation of one form of car embodying the invention.

F ig. 2 is a sectional view taken .2 of Fig. 1.

Fig. l) is an enlarged sectional view with parts omitted taken on line 99 of Fig. 1.

Fig. 10 is an enlarged sectional view with parts omitted taken on line 10-10 of Fig. 1.

Fig; 1.1 is a view showing in elevation one of the reinforcement engaging projections shown in plan in Fi 7.

Fig. 12 is a sectional View through a portion of the bottom and wall of a car showing a concrete body, a. concrete bottom andconcrete sidewalls and end walls, there being suitable metal remforcement in said bottom and walls. Extendinglongitndinally of the car, at th bottom thereof, is a metal member 1 which is in the form of a beam or girder. Qhe draw bars :2 are connected to this longitudinal member.

At the bottom of the car body, preferably opposite the floor, I provide a metal frame 3 which extends all the wav around the body forming a metal rectangle. In each endof the car at the point where it is connected with the truck I provide a transverse metal member 4. which is preferably made up of two sections, the inner ends thereof being connected to the longitudinal member 1. (See Fig. 7).

I also prefer to provide angle members 5, which. are connect-ed at one end with the 1011- gitudinal member 1 and at the other end with the transverse member 4. This construction may be formed in any desired man- 1101'. but as herein shown I provide plates 6,

b v means of which the members 5 are con nected with the members 4 and 7, by means ofwhich members 5 are connected with the member 1. A metal piece 8 connects the two sections of the transverse member 4 and. eX-

lends across the top of the member 1. Re-

inforcinc metal pieces 9 are embedded in the side wall 10 of the car and are connected ,with' plates 6 and transverse members 1-.

(See Figs. 7 and 10).

I prefer to provide at the top of. the car a metal. framell which extends along both sides and both ends and which forms :1 rectangular metal frame. The metal frames 3 and 11 are preferably connected together at thecorners by the metal pieces 12. thus forming a complete box metalframe which forms the corners and the top portions of the walls of the car. The reinforcing pieces 9 extend through the top member of the frame 11. (See Fig. 10).

Metal plates 13 are provided, said plates connecting the. side members of the frame 3 with the ends of the transverse members 4. (flee Fig. 11).

The tracks 13 are connected with the metal members 1 and l in any desired manner and by the ordinary king pins ll.

The side walls 10 are provided at the point where the transverse metal member 4 1s 10- -ated with reinforced ribs 15. These Walls are also provided at intervals with reinforced ribs lti and the bottom is also provided with reinforced ribs 17, integral with the floor. the inner ends thereof abnttine' Patented.

longitudinal metal member 1. The floor and ures "there are a series 24 at the bottom of these ribs.

ing metal members which preferably inter lock. One method of inserting these memhers isshown in Figs. 5 and 6. In these figof floor reinforcing members 18, which floor members are bent up at the ends as shown nect with the longitudinal wall reinforcing members. 19. The walls are preferably also provided with the. diagonal reinforcing members 20 and 21, which are connected with the metal frames 3- and 11. It will be noted that these diagonal members are placed more closely together at the points Where the greater strains and stresses are located, that is, near the ends of the car where the -car body is connected with the trucks.

The concrete ribs 17 at the bottom of the car are preferably provided with the inclined reinforcing members 22, which are in the form of a truss, the outer ends of which are connected with the plates 23. These plates are connected with the metal frame 3 and extend alOng the ends of the ribs 17. .1 prefor also to provide the metal corner pieces The members 22 extend entirely across the car as illustrated in Fig. 2, preferably passing above longitudinal member 1, and are similarly connected at their opposite ends. I also prefer to provide these ribs with a similar reinforcing metal member 22, which extends below the member 1. I also prefer to provide metal reinforcing members 26 whicn connect. the corner pieces 24 and the frames 3 and 11. Along the walls 10, at other places than where the ribs occur, I provide reinforcing metal pieces 27 (see Fig. 8), which connect the frames 3 and 11. The reinforcing pieces 9,, 26 and 27 are preferably made adjustable as by means of nuts and screw threads, as shown in Figs. 8, 9 and 10.

The reinforcing may be connected pass through the frame 3 and are held in place by the-nuts 29. These reinforcing members may be held to the top by means of the heads 30, or in any other desired manner At the ends of the car body I prefer to provide members 27, fpr example,

the reinforcing members '30 (see Fig. 3), which extend across the end and part way along the sides. provide the reinforcing members 31 which extend part way across the end and part way' along the sides, as shown in Fig. 3. The

members 30 and 31 arc preferably in the same horizontal. plane although this relation may he changed if desired.

I prefer to provide at the ends the inclined reinforcing members 32 which are connected with the along the sides in the inclined position, as

,in F ig. 5 and con-..

' side walls act as to the eyebolts 28 which lateral and will I also prefer to floor-and which extend shown in Fig. 5, and which then extend across the ends through the ribs (See Figs. 2 and 5).

The metal members 4 act as bolsters and I prefer to provide reinforcement engaging projections 34 to be attached to said mem bers -l and also the central longitudinal memher or sill 1. One of these reinforcement engaging projections is illustrated in Fig. 11 and may consist of angle pieces, one angle of which is connected to the member with which the device is associated, the other angle projecting therefrom and being provided with one or more grooves 3at -to receive the central reinforcing member or -members. The longitudinal member 1 may be made in any desired manner and as herein shown is of box girder construction comprising two side members suitably connected together and provided with a space between them. I prefer to provide at intervals between these members the connecting pieces 1. The draw bar at each end passes into this space and there are opposed inwardly projecting members 35 (see Fig. 7) between which the draw bar passes.

In Fig. 4 I have shown a modified construction wherein the reinforcen'ient consists of an expanded metal or woven metallic section-10. It will be seen that in this construction I provide a concrete car body having a concrete floor with metal reinforcement therein and metal members 'or frame pieces connected with thebody, the floor reinforcement interlocking with the metal memhere. It will further be seen that the longitudinal metal member acts as a beam to carry part of the load of, the body and that the side walls, which are integral with the concrete floor, have exposed top and bottom metal members, the reinforcement in the side walls being coiinected therewith. The girders to carry a portion of the load of the car body, the entire structure forming as it were a unitary car body. The parts are also arranged to proper y take c'arefof the strain and stresses due to the draw bar pull both longitudinal and also take care of the stresses and strains due to the connection of the body with the trucks. v i It will further be noted that the concrete ribs at the bottom of the car and the metal hansverse members 4 have their inner ends abutting the central metal member. In Fig. 12 I have shown a, modified construction wherein the longitudinal member 1 is provided at the top with the pieces 36. which are shown as? bars and which are connected at the top by the plate 37. The floor abuts these 2 bars, as shown, and there are provided reinforcing'members 38 which are connected at their inner .ends with the Z bars or central longitudinal member, their outer ends being bent up into the walls as shown.

There are also the looped or truss reinforc- 'bers 40, which connect with the opposite sides of the frame 3 and which extend entirely across. the bottom. The'members 38 are located at intervals all along the bottom of the car while the members 39 and 40 are only at the points where the fioor ribs or beams 17 are located. The members 38 may also be used in the construction shown in Figs. 1 and 8.

Fig. 9 shows a construction where the reinforcing members in the reinforced ribs 17 are arranged somewhat different from that shown in iFig. 2. In this construction member 22 is arranged as shown in Fig. 2 but the other member 22* instead of crossing the member 22 is attached to the parts 23 and 24 in the same horizontal plane.

I have described in detail a particular -construction embodying my. invention, but

it isof course evident that the parts may be varied in form, construction and arrange ment without departing from the spirit of the invention as set forth in the claims hereto appended, and I therefore do not limit myself to the particular construction shown.
